SANDING DEVCE.

Specification of Letters Patent.

Patented Nov.. 2li, llvtti.

Application filed April 20, 1916. Serial No. 92,472.

17 o all whom t may concern:

Be it known that I, VILLIAM P. Toonen, a citizen of the United States, residing at Flatbush, Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Sanding Devices, of which the following is a specification.

This invention relates to sanding or antiskidding devices Vfor automobiles or similar vehicles.

The principal object of the invention is .to provide a device of the character mentioned which will'satisfactorily permit of the distribution on to the surface of the roadway, quantities of sand, fine gravel or other similar granular material having the natural qualities of sand; delivering the sand in proximity to the driving wheels of the automobile and in the normal to permit the driving wheels to take effective driving purchase lagainst the roadway and at the same time positively preventing the -vehicle from skidding on slippery surfaces of the roadway.

Another and essential object of the invention resides in the distribution of sand or a similar material, respectively 'at the side of the driving wheels so as to arrest the tendency of the vehicle t0 skid in either direction. ln this manner the frictional surfaces between the roadway and the driving wheels of the vehicle will possess mairimum elliciency and the operation of retarding the tendency to skid is thereby perfected.

With the above and other objects in view which lwill appear as the nature of the invention is better understood,`the same consists in the improved construction and novel arrangements of parts which will hereinafter be nfully described and particularly pointed out in the claim.

ln the accompanying drawings,` has been' illustrated, a single and preferred form of the invention, it being, however, understood i that no limitations are necessarily made to the precise structural details therein eX- hibited," but that changes, alterations and modifications within the scope of the claim may be resorted vto when desired.

in the drawings :-Figure l, is a bottom plan view oi?v a portion of an automobile t7: `plimaticui of the invention no, die diei-...ributing valves being shown Fig. 2 is a vertical section through a portion of the floor of a vepath thereof so as uting pipe `minallv arranged with such hicle showing the application of the invention thereto. Fig. 3 is a perspective view of a section of the valve plate.

l do not wish to limit myself to the specific location of the sand container upon the vehicle and it is desired that it be understood that the arrangement herein illust'rated is only illustrative of one way whereby sand or like material may be temporarily stored and carried upon the vehicle. It is stated, however, that l do not wish to ar range-the sand container so that the sand may have an uninterrupted flow by its own gravity to the discharge or distributing pipes to be hereinafter referred to.

T he Idevice consists of one or a plurality of@ hoppers or containers l-1, fixedly mounted upon the under side of the frame of the vehicle, the latter being conventionally shown in dotted lines in Fig. 1. These hoppers have their large upper ends disposed in vertical alinement with openings formed in the. floor (A), of the vehicle and it is preferred that the floor be provided with a removable section (B), which may be closed over the upper ends of the hoppers normally. This' arrangement permits the operator to readily till the hoppers with sand as the occasion necessitates. I f Each hopper is provided with a distribpipe 3, the upper ends of which being ar-v ec j 2, and an outer distributingA ranged to open into the hoppers as illus- 'I trated in Fig. 2. A valve mechanism 4, is employed for the purpose of normally closing the pipes 2 and 3, said mechanism consisting principally of a Yplate 5, having sectionstS-G working in the hoppers at the lower ends thereof. At one side the plate is p provided with a stop flange 7, adapted to abut against the hoppers as shown in Figs. fand 2 and thereby preventthe plate from rod 8, whichextends in a longitudinal direction'under the fra-me of the vehicle and at its forward end, the rod has pivotal connection at 9, with a rocking lever l0. This u lever extends -in an upward direction through the floor of the car and it is terregard to the e operatcfrA ne same tra,

operatorie seat as to p rn readily grasp and ce Jol t being'accidentally moved entirely from the is controlled mani requisite time. The valve plate has its sections 6 6, formed each with a discharge slot l1, adapted to aline 'with the distributing pipes 2 `and 3, when the rocking lever 10, is moved in one direction. At another time the portions12, of the valve plate are adapted toA close over the upper ends of the pipes 2 and 3, (see Fig. 2').

In carrying the invention into practice, regard has been given the peculiar angular relation'of the pipe 3, to the next adjacent pipe 2, of each hopper whereby when the Valve mechanism is controlled for the pur-v pose of discharging the sand on to the roadway, the sand will. come from the discharge pipes in a continuous stream or lilm1ike fashion at points respectively at the 'opposite sides of the driving wheels of the lvehicle. This gives an uninterrupted or continuous friction surface between the driving wheels and the natural or slippery surfacesy of the roadway. The result which follows this stated arrangement of the distributing pipes issuch that the skidding of the vehicle is retarded almostvinstantly. .The sand is distributed in the same manner against both of the driving Wheels. The outer pipe 3, extends over and beyond the tread of the driving wheel and at a point in spaced rela'- tion theretoat the front side thereof.v The 80 inner pipe 2, is arranged substantially in converging relation to the outer pipe and it extends loutwardly .and slightly rearwardly as shown both -in Figs. l and 2.
